Question

Answer

what is artificial lift

POil is a fluid and the fluid column in a wellbore can be several 100 m high. This fluid column is very heavy and the reservoir pressure may not be sufficient to push the oil to the surface. Artificial lift helps by using pumps to help bring the oil to the surface

type of agreement is usually put into place where several companies would like to place a reservoir under secondary recovery

unit agreement

In-Situ Combustion

pumps air down the wellbore and lights the reservoir on fire. The heavy oil burns giving off heat that lowers viscosity and actually does some refining underground.
